Book Description
The Pathanamthitta District consists of three natural divisions viz, the lowlands, midlands and highlands. The topography of the district is highly undulating with hills and valleys. The vegetation is divided into 3 categories such as lowland vegetation, midland vegetation and upland vegetation. The Flora presents a systematic account of a total of 1249 species belonging to 658 general of 148 families of seed plants. The species index is registered as 460/1000 sq km which is comparatively very high and indicates the richness of the floristic diversity of the district. Seven new species and two new varieties have been discovered from the district. An analysis of the flora showed that 260 species are endemic which formed 22% of the total species. About 200 species are rare and 175 are severely threatened; most of which are local endemics. A total of 90 wild relatives of cultivated crop plants have been collected. Each species is provided with detailed up-to-date nomenclatural citations including synonyms if any, descriptions, phenology, distribution and notes on ecology, nomenclature, uses etc, if any. Illustrations of good quality of 59 species are also provided. The comprehensive floristic account will be of immense use to the botanists, agriculturists, foresters, pharmacists, phyotochemists, nature conservationists, ethnobotanists and to all the scientists working in other allied disciplines. Contents Chapter 1: Introduction; Chapter 2: Area of Study; Chapter 3: Vegetation; Chapter 4: Review of Earlier Work; Chapter 5: Present Work; Chapter 6: Floristic Analysis; Chapter 7: Threats of the Flora; Chapter 8: Proposed Area for Conservation; Chapter 9: Systematic Treatment.

Book Description
Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the first volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that were designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. This first volume in the series focuses on the Western Ghats and Sri Lanka, construed as forming a community of species because of their shared biogeographical history. The volume explores the diversity and conservation efforts of the extraordinarily rich species found here, including plants, many of which are found nowhere else in the world; forests, which face tremendous population pressure and have been dramatically impacted by demands for timber and agricultural land; as well as the hotspot’s diverse mammals, birds, insects, and amphibian species, and more. The volumes in this series will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution.

Book Description
This book gives insight into several aspects of the microbiology, biotechnology, and ecosystem sustainability of special and under-explored regions, that captivate human beings by their natural richness, their extensive biodiversity, the extraordinary forms of adaptation of the living beings that they inhabit, and even that keep living secrets as is the very origin of life. The chapters emphasize all aspects of biological diversity-its description, analysis, and conservation, and its controlled rational use by humankind. Also, the book is elaborated from a wide and multidisciplinary point of view. It presents reviews, research papers, comments, and research notes on biodiversity, ethnobiology, geoscience, chemistry, biological conservation, biotechnology, and ecosystem sustainability Two hotspots are the reference for this enriching book that describes details of extraordinary areas of the planet, from Cuatrociénegas, Coahuila (Mexico) to the Southern Western Ghats (India). The book will contribute to dealing with the practicalities of conservation management, economic, social, and political issues. It provides a forum for examining conflicts between sustainable development and human dependence on biodiversity in agriculture, environmental management, and biotechnology, and encourages contributions from developing countries to promote broad global perspectives on matters of biodiversity and conservation.

Book Description
Ecohydrology of Kerala: River Catchments and Coastal Backwaters presents 20 years of research to provide suggestions for sustainable management solutions for issues surrounding the urbanization of the rivers of Kerala. This helps identify major issues and develop management strategies. Themes explored include biogeochemistry of rivers/estuarine systems, productivity and trophic status, biology: fauna and flora, biodiversity, threats and conservation, invasive species and impact on riverine ecology, landscape/land use/land cover change in the catchment, socioeconomic status of catchment population, economic and livelihood activities along the river courses/estuaries (river and estuarine tourism, sand extraction, fisheries), pollution monitoring and assessment, impacts of climate change, and more. This book can be used as a tool in the holistic management of resources, and to devise proper mitigation measures. The content of the book is a model for other tropical regions and countries with rapidly developing economies and populations - Presents spatial maps and easy to follow figures in each chapter, aiding in a foundational understanding of the topic - Provides a fully comprehensive overview, including biogeochemistry, ecology, productivity, livelihood, socioeconomic aspects, and governance of the rivers - Includes specific cases of ecohydrology in the river basin, especially from rivers and coastal lakes of Kerala

Book Description
This new 5-volume set, Ethnobotany of India, provides an informative overview of human-plant interrelationships in India, focusing on the regional plants and their medicinal properties and uses. Each volume focuses on a different significant region of India, including Volume 1: Eastern Ghats and Deccan Volume 2: Western Ghats and West Coast of Peninsular India Volume 3: North-East India and Andaman and Nicobar Islands Volume 4: Western and Central Himalaya Volume 5: The Indo-Gangetic Region and Central India With chapters written by experts in the field, the book provides comprehensive information on the tribals (the indigenous populations of the region) and knowledge on plants that grow around them. Each volume includes an introductory chapter with an overview of the region and then goes on to cover ethnic diversity and culture of the ethnic tribes plants used for healing and medical purposes for humans and animals ethnic food plants and ethnic food preparation specific information on the ethnomedicinal plants, the parts used, and the diseases cured other uses of plants by the ethnic tribes, such as for fiber, dyes, flavor, and recreation conservation, documentation, and management efforts of the ethnic communities and their plant knowledge The books include the details of the plants used, their scientific names, the parts used, and how the plants are used, providing the what, how, and why of plant usage. The volumes are well illustrated with over 100 color and 130 b/w illustrations. Together, the five volumes in the Ethnobotany of India series bring together the available ethnobotanical knowledge of India in one place. India is one of the most important regions of the old world, and its ancient and culturally rich and diverse knowledge of ethnobotany will be valuable to many in the fields of botany and plant sciences, pharmacognosy and pharmacology, nutraceuticals, and others. The books also consider the threat to plant biodiversity imposed by environmental degradation, which impacts cultural diversity.
